IMPROVEMENT IN MACHINES FOR TENONING SPOKES AND BORING FELLIES.

Specification forming part of Letters Patent No. 122,551, dated January 9, 1872.

To all whom 'it may concern:

Be it known that I, JOSEPH BAUMAN, of Shepherdstown, in the county of Cumberland and State of Pennsylvania, have invented an Improvement in Machines for Tenoning Spokes and Boring Fellies; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing making part of this specification- Figure l being a top view of the machine 5 Fig. 2, a side view of the same; Fig. 3, a transverse vertical section of the same in a plane indicated by the line .r fr, Fig. l; Figs. 4, 5, and 6, views of parts detached; ,Fig 7, a view representing a modication of one part of the machine.

Like letters designate corresponding parts in all of the gures.

A suitable frame, A, substantially of the construction shown, is provided, having a longitudinal vertical opening, a, in the middle at one end for the reception and free manipulation of the wheels to be formed. Upon the other end of the frame is located the spoke-tenoning and felly-boring device. At the open end of the frame are two transverse ways, on the two sides ofthe open space, in which ways are located sliding bearings B B for holding and adjusting the positions ofthe hubs of the wheels to be put together. Each bearing B is provided with a chuck, C, for clamping upon and holding in a concentric position one end of ahub. This chuck or clamping device, as I construct it, is substantially as represented in Figs. 3, 4, 5, and 6. There is a disk, b, having three or more radial openings or notches, c o c, in which slide jaws d d d for grasping the end of thehub. This disk has a shaft or long journahf, which extends outward through and turns in its sliding bearing B. Behind the disk b is anotherdisk, g, which turns freely on the journal fof the said disk b and has a spiral groove, h, Fig. 6, in its face, into which spiral groove suitably-formed projections on the jaws dddt and travel therein. The disk g has holes in its periphery, as shown, for inserting a pin or lever to hold or turn the disk one way while the disk b is turned or held the other way, and the disk b may have similar holes; or both disks may have any equivalent means to hold and turn them by. When the disks are turned in opposite directions the jaws cl cl al traverse the spiral groove lL in the disk g, the effect of which, when turning in one direction, is to move the jaws radially outward and, when turning in. the other direction, to force the jaws inward equally and thus clamp the hubs, whatever may be the size thereof. A hub, being clamped in the two chucks, is readily moved by the bearings B B in the transverse ways of the frame, so as to adjust it in exactly the right position for cutting the tenons on its spokes by the tenon-cutting device in place. This adjustment is made by a single screw, i, turning in the side of the frame and operating in a nut, k, projecting down from the sliding bearing B above, as shown in Fig. 3. If it is preferred to have a simple hub-holder tting in the bores of the hubs, a device, as represented in Fig. 7, may be employed. Thus, in the bearingB turns a shaft, l, leaving a screwprojection, m, which is turned into the bore of the hub and holds it, while the shaft l serves, also, as a journal to turn in the bearing B. This device answers for a cheap machine, but the outside clamping device is preferable.. On one of the bearings B B is located a spokeguide, D, which is pivoted to the bearing so as to swing in a plane parallel with the plane of the spokes. It has a gauge-rod, n, projecting inward to the position of the spokes. When a spoke is to be driven into the hub the guideD may be brought into an upright position, as in Fig. 3, to determine the exact position of the spoke; and then it may be turned aside so as not to be in the way of driving the spoke. Thus the gauge or guide is always ready at hand to guide the adjustment of the spokes, and never in the way thereof. The spoketenoning and felly-boring device E is located on a frame or base, p, which is adjustable to any position on the main frame v A by a clamp and wedge underneath the main frame or any equivalent means. The tenoncutter and boring-bit are'secured in turn to a crank-shaft, G, which has a longitudinal movement equal to the distance it is required to travel in the operation, and a coiled spring, r,

lits thereon and by its power feeds the shaft' and the cutter or bit attached thereto automatically. It is drawn back after each cutting or boring by a lever hold-back, H, operating by an arm, s, on its shaft or journal, and a conmeeting-rod, t, acting upon the cutter-shaft. The lever holdback His held back by a catch, u, as shown. There is a gauge, I, on the side of the frame adjustable to dilerent positions, according to the length of spokes required, to saw the spokes oi' to uniform len ,Qths by; and the tenen-cutting device is to be adjusted to correspond in position thereto, so as to cut the tenons Without further adjustment. The tellyholder K is removable from the frame A, as it Would be in the Way of the spokes of the Wheels when cutting the tenons thereof. It is located as shown in dotted lilies, and is attached by a clamp and Wedge or other means. Its peculiarity consists in two pairs ot' projecting pins7 o o and w w, the former to guide the position of the fellies so that the holes bored therein shall be radial to the circle of their curve7 and the other pair fw w to steady the fellies in place when withdrawing the auger or bit. The fellies are placed between the two pairs.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. A wheelwrights machine provided with transverse-sliding bearingsB B having the outside clainping-chucks C C and with the spoketenoning,` and telly-boring device E, constructed with the ganged spring-feeding cutter-shari: G and hold-back H, all arranged and operating together, substantially as herein specified.

2. The swinging spoke-guide D when arranged upon one of the sliding bearings B B and operating in combination with the said bearings, substantially as herein specified.
